Associations between blood donor sex and age, and outcomes of transfused newborn infants.

BACKGROUND: It is controversial whether the sex or age of red blood cell (RBC) donors affects mortality or morbidities of transfused newborn infants. We assessed these issues using a multi-year, multi-hospital database linking specific outcomes of neonatal transfusion recipients with RBC donor sex and age. STUDY DESIGN AND METHODS: We performed retrospective analyses of all neonates receiving ≥ one RBC transfusion during a 12-year period in all Intermountain Healthcare hospitals, matching mortality and specific morbidities of each transfusion recipient with the sex and age of each donor. RESULTS: There were 6396 RBC transfusions administered to 2086 infants in 15 hospitals. A total of 825 infants were transfused exclusively with RBC from female donors, 935 infants were transfused exclusively with RBC from male donors, and 326 infants were transfused with RBC from both female and male donors. No differences in baseline characteristics were identified among the three groups. Infants who received blood from both male and female donors had more RBC transfusions (5.3 ± 2.9 transfusions if received both male and female donor blood vs. 2.6 ± 2.2 if received blood from only one sex, mean ± SD, p < .001). We identified no significant differences in mortality or morbidities associated with the sex or the age of blood donors. Similarly, an analysis of matched vs. mismatched donor/recipient sex revealed no associations with death or neonatal morbidities. CONCLUSION: These data support the practice of transfusing newborn infants with RBC obtained from donors of either sex and regardless of donor age.

High frequency of upper aerodigestive tract manifestations in mucous membrane pemphigoid.

OBJECTIVE: The objective of this study was to evaluate the frequency of upper aerodigestive tract involvement in patients with mucous membrane pemphigoid associated with desquamative gingivitis. SUBJECTS AND METHODS: Data from 25 patients were collected by retrospective chart review. Their upper aerodigestive had been evaluated using a conventional flexible fiberscope. Oral disease activity was quantified on the basis of the Mucous Membrane Pemphigoid Disease Area Index activity score. RESULTS: Lesions of the upper aerodigestive tract were confirmed in nine symptomatic patients (9/25, 36%), of which five (5/25, 20%) had laryngeal involvement. No lesions were seen in the asymptomatic patients on fiberscope examination. There was a statistically significant difference in the symptoms, high oral disease activity score, and linear IgA deposition on direct immunofluorescence between patients with and without upper aerodigestive tract lesions (p = .001, .001, .002, respectively). CONCLUSION: The high frequency of considerable complications highlights the importance of confirming the presence of upper aerodigestive tract involvement in patients with mucous membrane pemphigoid having desquamative gingivitis. Signs including the presence of symptoms, high oral disease activity score, or linear IgA deposition on direct immunofluorescence might indicate a higher risk of upper aerodigestive tract involvement.

Evaluating emergency-release blood transfusion of newborn infants at the Intermountain Healthcare hospitals.

BACKGROUND: An emergency-release blood transfusion (ERBT) protocol (uncrossmatched type O-negative red blood cells, AB plasma, AB platelets) is critical for neonatology practice. However, few reports of emergency transfusions are available. We conducted an ERBT quality improvement project as a basis for progress. STUDY DESIGN AND METHODS: For each ERBT in the past 8 years, we logged indications, products, locations and timing of the transfusions, and outcomes. RESULTS: One hundred forty-nine ERBTs were administered; 42% involved a single blood product, and 58% involved two or more. The incidence was 6.25 ERBT per 10,000 live births, with a higher rate (9.52 ERBT/10,000) in hospitals with a Level 3 neonatal intensive care unit (NICU) (p < 0.001). Seventy percent of ERBTs were administered in a NICU and 30% in a delivery room, operating room, or emergency department. Indications were abruption/previa (32.2%), congenital anemia (i.e., fetomaternal hemorrhage; 15.4%), umbilical cord accident (i.e., velamentous insertion; 15.0%), and bleeding/coagulopathy (12.8%). Fifty-eight percent of those with hemorrhage before birth did not have a hemoglobin value reported on the umbilical cord gas; thus, anemia was not recognized initially. None of the 149 ERBTs were administered using a blood warmer. The mortality rate of recipients was 35%. CONCLUSION: Based on our findings, we recommend including a hemoglobin value with every cord blood gas after emergency delivery to rapidly identify fetal anemia. We also discuss two potential improvements for future testing: 1) the use of a warming device for massive transfusion of neonates and 2) the use of low-titer group O cold-stored whole blood for massive hemorrhage in neonates.

Updates Regarding Diagnostic Adjuncts for Oral Squamous Cell Carcinoma.

The 5-year survival rate for oral cancer (66%) is still one of the lowest among major human cancers, and delayed diagnosis until an advanced stage is thought to be the main factor contributing to this low survival rate. The detection and diagnosis of oral cancer is currently based on clinical visual examination and histopathological evaluation of a biopsy specimen. In response to the need for early detection of oral cancer, several diagnostic adjuncts have been developed and sold commercially over the years, including vital tissue staining, brush cytology, light-based visualization adjuncts, and the most recently developed test for salivary biomarkers for oral cancer. The purpose of this article is to review the current knowledge and research regarding these diagnostic adjuncts developed for early detection of oral cancer. Clinicians are best served by an awareness of the advantages and disadvantages of each adjunct, and to always consider and correlate with the clinical findings when interpreting the test results from these adjuncts.

Levels of potential oral cancer salivary mRNA biomarkers in oral cancer patients in remission and oral lichen planus patients.

OBJECTIVES: To gather preliminary data concerning the feasibility of using seven salivary mRNAs-IL-8; IL-1ß; dual specificity phosphatase 1 (DUSP1); H3 histone family 3A (H3F3A); ornithin decarboxylase antizyme 1 (OAZ1); S100 calcium-binding protein P (S100P); and spermidine/spermine N1-acetyltransferase 1 (SAT1)-for detecting development of oral squamous cell carcinoma (OSCC) in oral lichen planus (OLP) patients and OSCC patients whose disease was in remission. MATERIALS AND METHODS: Saliva samples were collected from five study groups (25 subjects/group): newly diagnosed OSCC, OSCC-in-remission, disease-active OLP, disease-inactive OLP, and normal controls. The salivary mRNA levels were determined by a pre-amplification RT-qPCR approach with nested gene-specific primers. Mean fold changes between each pair of study groups were analyzed by the Mann-Whitney U test. RESULTS: Salivary levels of OAZ1, S100P, and DUSP1 mRNAs were significantly higher in newly diagnosed OSCC patients, compared to: (1) normal controls (p = 0.003; p = 0.003; and p < 0.001, respectively); (2) OSCC-in-remission (p < 0.001; p = 0.001; and p < 0.001, respectively); (3) disease-active OLP (p < 0.001; p = 0.016; and p < 0.001, respectively); and (4) disease-inactive OLP (p = 0.043; p < 0.001; and p < 0.001, respectively). No significant differences were found in the levels of salivary IL-8, IL-1ß, H3F3A, and SAT1 mRNAs between newly diagnosed OSCC patients and the normal controls (p = 0.093, 0.327, 0.764, and 0.560, respectively). CONCLUSION: Salivary OAZ1, S100P, and DUSP1 mRNAs are candidate biomarkers for detecting OSCC development in OSCC patients in remission and in OLP patients. CLINICAL RELEVANCE: The results of this study serve as the basis for a further large-scale study which may lead to a non-invasive screening method for early detection of OSCC.

Low-Titer Type O Whole Blood for Transfusing Perinatal Patients after Acute Hemorrhage: A Case Series.

Objective Acute and massive blood loss is fortunately a rare occurrence in perinatal/neonatal practice. When it occurs, typical transfusion paradigms utilize sequential administration of blood components. However, an alternative approach, transfusing type O whole blood with low anti-A and anti-B titers, (LTOWB) has recently been approved and utilized in trauma surgery. Study Design Retrospective analysis of all perinatal patients who have received LTOWB after acute massive hemorrhage at the Intermountain Medical Center. Results LTOWB was the initial transfusion product we used to resuscitate/treat 25 women with acute and massive postpartum hemorrhage and five infants with acute hemorrhage in the first hours/days after birth. We encountered no problems obtaining or transfusing this product and we recognized no adverse effects of this treatment. Conclusion Transfusing LTOWB to perinatal patients after acute blood loss is feasible and appears at least as safe a serial component transfusion. Its use has subsequently been expanded to multiple hospitals in our region as first-line transfusion treatment for acute perinatal hemorrhage. Key Points Low-titer type O whole blood (LTOWB) was our initial transfusion product for 30 perinatal patients with acute hemorrhage. Twenty-five of these were obstetrical patients and five were neonatal patients. We encountered no problems with, or adverse effects from LTOWB in any of these patients. LTOWB transfusions to women were ten days since donor draw (interquartile range, 8-13) and to neonates was six days (5-8).

Oral mucosal findings related to tobacco use and alcohol consumption: a study on Swiss army recruits involving self-reported and clinical data.

PURPOSE: The aim of the present study was to assess the oral mucosal health status of young male adults (aged 18 to 24 years) in Switzerland and to correlate their clinical findings with self-reported risk factors such as tobacco use and alcohol consumption. MATERIALS AND METHODS: Data on the oral health status of 615 Swiss Army recruits were collected using a standardised self-reported questionnaire, followed by an intraoral examination. Positive clinical findings were classified as (1) common conditions and anatomical variants, (2) reactive lesions, (3) benign tumour lesions and (4) premalignant lesions. The main locations of the oral mucosal findings were recorded on a topographical classification chart. Using correlational statistics, the findings were further associated with the known risk factors such as tobacco use and alcohol consumption. RESULTS: A total of 468 findings were diagnosed in 327 (53.17%) of the 615 subjects. In total, 445 findings (95.09%) were classified as common conditions, anatomical variants and reactive soft-tissue lesions. In the group of reactive soft-tissue lesions, there was a significantly higher percentage of smokers (P < 0.001) and subjects with a combination of smoking and alcohol consumption (P < 0.001). Eight lesions were clinically diagnosed as oral leukoplakias associated with smokeless tobacco. The prevalence of precursor lesions in the population examined was over 1%. CONCLUSIONS: Among young male adults in Switzerland, a significant number of oral mucosal lesions can be identified, which strongly correlate with tobacco use. To improve primary and secondary prevention, young adults should therefore be informed more extensively about the negative effects of tobacco use on oral health.

Surgical considerations and management of patients with mucocutaneous disorders.

Surgeons may be confronted with providing periodontal plastic or implant therapy for patients with gingival manifestations of systemic conditions. These conditions (often referred to as mucocutaneous disorders) commonly present with features of desquamative gingivitis, which was once believed to represent a disease entity. However, today, the term desquamative gingivitis is used to describe clinical features of various local or systemic diseases or disorders that result in chronic gingival lesions characterized by epithelial desquamation, erythema, ulceration, and/or vesiculobullous lesions of the gingiva. Often, other oral tissues also are involved. Mucocutaneous disorders include such disease entities as lichen planus, graft-versus-host disease, pemphigoid, pemphigus vulgaris, lupus erythematosus, erythema multiforme, and linear IgA disease. Surgeons should be able to recognize these disorders and have the tools necessary to treat these conditions so that they can render the appropriate surgical care. This article describes the diagnosis, etiology, and clinical manifestation of these disease entities, as well as the surgical considerations and management in providing care to these patients.

Acantholysis may precede elevation of circulating anti-desmoglein 3 antibody levels in pemphigus vulgaris presenting with desquamative gingivitis.

Pemphigus vulgaris (PV) is an autoimmune, blistering disease that affects the mucosa and skin. The current theory favors the concept that anti-desmoglein (Dsg) 3 autoimmunity is the only pathogenic event needed to induce acantholysis. However, a few cases of active PV in the oral cavity had no detectable anti-Dsg 3 antibody. The aim of this study was to evaluate the differences in clinical and laboratory findings, whether or not the anti-Dsg 3 antibodies were present. This study was based on a retrospective review of 10 PV cases. The evaluation of the circulating autoantibody titers to Dsg 3 was conducted by using enzyme-linked immunosorbent assay (ELISA). An index value of 20 or more was used as the cutoff for a positive reaction. Only five of the 10 PV cases had a positive Dsg 3 ELISA. There were no differences in clinical, cytological, histopathological, and direct immunofluorescence findings, whether or not the anti-Dsg 3 antibodies were present. Of the five patients with a negative reaction at the time of diagnosis, the Dsg 3 ELISA became positive in the follow-up period in three cases. In the remaining two cases, the Dsg 3 ELISA was consistently negative for 18 months. Dsg 3 ELISA was negative early in some PV cases. Therefore, PV acantholysis may precede the elevation of circulating anti-Dsg 3 antibody levels. The diagnosis of PV should be considered based on comprehensive clinical, histopathological, and immunofluorescent criteria.

Exophytic mass of the gingiva as the first manifestation of metastatic pulmonary adenocarcinoma.

BACKGROUND: Metastasis of a malignant tumor to the oral cavity is rare, but it can be the first manifestation of a primary tumor. METHODS: The clinicopathologic features of a gingival metastasis originating from lung adenocarcinoma in a female patient are described. A 57-year-old woman showed a rapidly growing, painless, exophytic mass in the left mandibular gingiva. The whole lesion was excised, and histologic and immunohistochemical analyses were performed. RESULTS: The histopathologic sections showed a proliferation of poorly differentiated spindle and pleomorphic cells. Because the differentiation between carcinoma and sarcoma of spindle cell tumors was difficult, additional immunohistochemical evaluation was performed. The intraoral healing after tumor removal was uneventful. The discrepancy between the histopathologic results and the clinical findings led to a thorough examination by the patient's physician. Finally, a biopsy of the lungs confirmed a poorly differentiated adenocarcinoma with multiple metastases, including the oral cavity. CONCLUSIONS: An exophytic lesion on the gingiva can be the first sign of metastatic adenocarcinoma to the oral mucosa. This case emphasizes that even apparently benign-looking gingival lesions in anamnestically healthy patients need to be examined histopathologically.

Disease progression from mucosal to mucocutaneous involvement in a patient with desquamative gingivitis associated with pemphigus vulgaris.

BACKGROUND: Pemphigus vulgaris (PV) frequently begins with oral lesions and progresses to skin lesions. A patient is described who developed skin lesions during follow-up and whose only initial symptom was desquamative gingivitis (DG). METHODS: A 31-year-old woman presented with a 2-month history of painful gingiva. The diagnosis of PV was made according to clinical, histopathological, and immunofluorescent criteria. Topical corticosteroid (0.1% triamcinolone acetonide) was provided for the treatment of DG. Evaluation of the circulating autoantibody titers to desmoglein (Dsg)1 and Dsg3 was conducted by enzyme-linked immunosorbent assay (ELISA). RESULTS: The gingival PV lesions went into remission with the use of topical corticosteroid, although the patient experienced occasional recurrent oral lesions that required retreatment. She had regular follow-ups and remained relatively stable for several months. However, relapse and worsening of the oral lesions and the onset of skin lesions occurred after 26 months. Using ELISA, a change in the autoantibody profile corresponding to the transition from mucosal PV to mucocutaneous PV was confirmed. In all ELISA studies conducted throughout the course of the patient's disease, the Dsg3 ELISA was consistently high ranging from 150 to 200. However, the Dsg1 ELISA remained low, ranging from 10 to 30. After 26 months, Dsg3 (index value of 150) and Dsg1 (index value of 114) ELISA levels were elevated, consistent with the transition to mucocutaneous PV. CONCLUSIONS: In cases in which the lesions are limited to the oral cavity, PV sometimes may be managed successfully using only topical corticosteroids. However, it may not be possible to reduce the circulating Dsg autoantibody titers without systemic immunosuppression. The sustained high Dsg3 antibody level may cause "epitope spreading" and induce skin lesions. It may be prudent to determine post-treatment levels of Dsg using ELISA and, in consultation with the physician, recommend the addition of systemic therapy if Dsg3 levels remain elevated.

Cinnamon products as a possible etiologic factor in orofacial granulomatosis.

OBJECTIVES: It has been reported that clinical changes due to hypersensitivity reactions to various foods, preservatives, and oral hygiene products may be consistent with the characteristic signs of orofacial granulomatosis (OFG). The objective of this study was to examine 37 well-documented cases of cinnamon-induced contact stomatitis for clinical and histological features consistent with a diagnosis of OFG. STUDY DESIGN: We reviewed the records of the 37 cases to screen them for the clinical and histopathologic features of OFG. RESULTS: Twelve patients showed clinical characteristics of OFG. The most commonly affected site was the gingiva. Focal non-caseating, epitheloid granulomas were observed in four histologic specimens. Multinucleated giant cells were observed in an additional four cases. CONCLUSIONS: Although OFG may have multiple etiologies, it is clear that, in some instances, a hypersensitivity reaction to cinnamon products can elicit lesions consistent with OFG.

Handheld tunable focus confocal microscope utilizing a double-clad fiber coupler for in vivo imaging of oral epithelium.

A reflectance confocal endomicroscope with double-clad fiber coupler and electrically tunable focus lens is applied to imaging of the oral mucosa. The instrument is designed to be lightweight and robust for clinical use. The tunable lens allows axial scanning through > 250 ?? ? m in the epithelium when the probe tip is placed in contact with tissue. Images are acquired at 6.6 frames per second with a field of view diameter up to 850 ?? ? m . In vivo imaging of a wide range of normal sites in the oral cavity demonstrates the accessibility of the handheld probe. In vivo imaging of clinical lesions diagnosed as inflammation and dysplasia illustrates the ability of reflectance confocal endomicroscopy to image cellular changes associated with pathology.

Periodontal status in patients with gingival mucous membrane pemphigoid.

BACKGROUND: Mucous membrane pemphigoid (MMP) describes an autoimmune disease with a range of variants, including those with oral, ocular, and cutaneous lesions. Persistent oral lesions, lack of effective oral hygiene, and plaque accumulation may increase the risk of long-term periodontal disease. However, to our knowledge, no studies have evaluated the relationship between the presence of gingival MMP and periodontal health. The purpose of this study was to evaluate the possible impact of gingival pemphigoid lesions on the human periodontium. METHODS: Twenty patients with histologic confirmation of subepithelial separation with or without direct immunofluorescence testing were randomly chosen to participate in a study evaluating their periodontal status. Parameters evaluated included plaque score, gingival index, bleeding index, probing depths, recession, clinical attachment level, mobility, furcation involvement, number of missing teeth, and Machtei criteria, a previously defined criteria for periodontitis. Individuals matched with respect to age, gender, and smoking history were selected and evaluated for the same parameters. RESULTS: MMP patients had statistically significant larger mean gingival index scores than age, gender, and smoking history matched controls. Plaque scores, bleeding index, mobility, furcations, clinical attachment level, recession, and periodontal status did not show statistically significant differences between MMP and control patients. A statistically significant difference in plaque index was found when patients with MMP in treatment were compared to patients with MMP in remission. Among patients with MMP, those diagnosed >5 years in the past had statistically significantly greater Class I furcation involvement and recession on facial and lingual surfaces of teeth. CONCLUSIONS: A relationship was found to suggest that patients with MMP exhibit more gingival inflammation than a control population. Among patients with MMP, patients currently in treatment have higher plaque indices than those in remission and not receiving treatment. Furthermore, when comparing patients with MMP who received a diagnosis>5 years in the past to those with a diagnosis in the past 5 years, statistically significantly greater Class I furcation and facial and lingual recession were measured. Long-term follow-up in this population may provide additional information as to periodontal progression in MMP versus control patients.

Distraction osteogenesis versus autogenous onlay grafting. Part II: biology of regenerate and onlay bone.

PURPOSE: Few studies have directly compared the quality of bone generated by distraction osteogenesis with that generated by autogenous onlay grafting. The purpose of this study was to compare rates of bone turnover at 5 months in bone produced by distraction osteogenesis and onlay grafting. MATERIALS AND METHODS: Alveolar defects created in jaws of American foxhounds were augmented with distraction osteogenesis or onlay grafting and allowed to heal for 5 months. The animals were then sacrificed and the jaws were resected and prepared for decalcified and undecalcified histologic examination. RESULTS: Both procedures produced bone containing a mixture of haversian systems and trabecular bone. A significantly greater ratio of osteoblast-covered bone surface to total trabecular bone surface (mean +/- SEM) was noted in distraction bone (0.124 +/- 0.049) compared to onlay bone (0.081 +/- 0.048) or control host bone (0.085 +/- 0.042 microm) (P < .05). In addition, significantly (P <.05) greater numbers of osteoclasts per microm of bone surface were noted in distraction bone (0.939 +/- 0.07) compared to onlay bone (0.605 +/- 0.06) or control host bone (0.725 +/- 0.08). No differences in rates of mineralization were noted between the groups. DISCUSSION: While bone from both experimental groups appeared adequate for implant placement, distraction bone appeared to be remodeling at a higher rate than either onlay or control bone. CONCLUSION: Given that the state of healing of the bone in each of these comparative groups was examined at a static point in time, it is premature to draw conclusions about the efficacy of one procedure over the other.

Oral lichen planus and malignant transformation: a retrospective follow-up study of clinical and histopathologic data.

OBJECTIVE: Patients in the stomatology service of the Department of Oral Surgery and Stomatology who were clinically and histopathologically diagnosed with oral lichen planus (OLP) in the years 1995 to 2001 were examined for a possible malignant transformation of a previously biopsied OLP site. METHOD AND MATERIALS: For the 145 patients included, the recordings were searched for initial localization and type of OLP lesion, potential noxious agents, distribution between symptomatic and asymptomatic OLP types, and for a malignant transformation of a known OLP site during the follow-up period up to December 2003. RESULTS: The group comprised 47 men and 98 women with a mean age of 56.3 years. Of the 497 lesions, almost half were classified as reticular or papular, predominantly located on the buccal mucosa, gingiva, and borders of the tongue. Four patients did not adhere to their scheduled control visits and were dropped from the study. During the follow-up period 4 patients developed malignant transformation of OLP. In 3 of these cases, dysplasia was present at the initial diagnosis of OLP. This results in a malignant transformation rate of 2.84% among the remaining 141 patients; if the 3 patients with initial dysplasia are excluded, the rate drops to 0.71%. CONCLUSIONS: Until further knowledge is derived from large prospective studies, the data supporting or negating a potential malignant character of OLP lesions remains inconclusive. Special emphasis has to be directed toward unified inclusion and exclusion criteria regarding clinical and histologic findings and identifiable risk factors to allow the comparison of different studies.

Clinical features of cinnamon-induced contact stomatitis.

Cinnamon flavoring agents are known to act on the mucosa as irritants or sensitizers. The objective of this study was to report on clinical and histologic features important in the diagnosis of cinnamon-induced contact stomatitis. We examined 37 past cases of contact stomatitis and identified clinical signs and symptoms and possible causes. The most common cause in the 37 cases was toothpaste; other causes were chewing gum and foods. Although various clinical findings were observed, some characteristics were evident. The most commonly affected site was the gingiva, which showed diffuse or generalized erythema and epithelial sloughing. It is important to identify the causative agents of such a disorder by understanding characteristic signs and symptoms and conducting an appropriate inquiry.

Treatment of refractory facial pain diagnosed as atypical trigeminal neuralgia: a case report.

This case report describes an effective treatment protocol, the healing process, and the recovery of the patient to a pain-free status after more than 25 years of failed treatment for facial pain. Features of this case report include: 1. A procedure to produce a phenomenon useful as a pathognomonic sign of autonomic nervous system neuropathy, as a determination of the location of the origin of pain, and as a monitoring device for the effectiveness of treatment. 2. A digital pressure intervention procedure that appears effective as a treatment modality to relieve pain and to effect healing. 3. A method to improve posture of the body affecting the relationship of the maxilla to the mandible, the dental occlusion, and the etiology of facial pain. 4. A description of the nature and intensity of the different levels of the pain experienced in the face from the most severe state of pain to a no-pain condition. 5. A diagnosis using a diagnostic term that has developed since the initial diagnosis of atypical trigeminal neuralgia in this case.

Clinical and diagnostic features of mucous membrane pemphigoid.

The aim of this study was to characterize the clinical and diagnostic features of mucous membrane pemphigoid (MMP). Five MMP patients were evaluated, and biopsies were obtained for routine histopathology and direct immunofluorescence. Circulating autoantibodies were verified by indirect immunofluorescence. Circulating immunoglobulin G autoantibody specific for 180 kDa bullous pemphigoid antigen (BP180) was evaluated by enzyme-linked immunosorbent assay (ELISA). All 5 patients complained of erythematous gingiva. Two patients had extraoral lesions involving the nasal mucosa, eyes, and skin. Histopathological confirmation was established for 4 of the patients, while direct immunofluorescence findings were positive in all 5. Although circulating autoantibodies were not identified by indirect immunofluorescence, the BP180 ELISA was positive in 3 cases. Both histopathological and direct immunofluorescence examinations are essential to establish a definitive diagnosis. Identification of circulating BP180 specific autoantibody shows promise.

Experimental chairside test for the rapid diagnosis of oropharyngeal candidiasis.

Oral infection with Candida fungal species is very common. Oral candidiasis is usually diagnosed by clinical appearance because no chairside diagnostic methods are available. In contrast, a rapid latex agglutination (RLA) test has proven useful for in-office diagnosis of vulvovaginal candidiasis. This study was undertaken to determine if the RLA technique might be used to provide a quick chairside test for oral candidiasis. Twenty-five patients participated in the study, including 21 patients with clinical evidence suggestive of oral candidiasis serving as the experimental group and 4 patients with apparent good oral health serving as controls. The presence of oral candidiasis was evaluated using RLA, fungal culturing, and cytology. RLA testing was consistent with established diagnostic tests in patients with oral candidiasis. However, RLA false positive results were noted, and the test is highly technique-sensitive and subjective. The technique is worthy of further study to determine its ultimate value in the diagnosis of oral candidiasis.
